Usually, rose buds should be harvested before opening, that is, when the longitudinal diameter of the bud is 3 times that of the calyx, the best harvest is collected, and the yield is reduced too early, and the quality is affected by the late flowering. Select healthy and full buds during the blooming period, and pick the petals of other delicate buds after they fully open. Flowers that open sporadically at other times should also be picked when they are fully open. Rose drying equipment, while drying roses can also collect rose cell liquid, kill two birds with one stone. Today we give a brief introduction to the air energy rose dryer.

Air energy rose heat pump dryer using low temperature, strengthen circulation air, strong moisture drying, to ensure the rose natural color, full shape, do not damage the pattern, do not destroy its natural efficacy, nutrients do not lose, heat pump dryer high degree of automation, do not need special care, drying process is all controlled by microcomputer.

1. Pretreatment of roses before drying

Some people in the industry carry out color protection treatment before drying roses, the specific implementation method is to change the PH value in the cell fluid of the flower material, or high temperature killing to increase the stability of the pigment, and kill or deactivate the enzyme activity in the material to carry out color protection treatment.

Two, rose layout

Layer the rose stamens into the material. 14P air energy heat pump drying integrated host with about 50 cubic polyurethane insulation drying room, a batch of flowers can be put into about 2000 pounds. The whole drying room can be loaded into 8 material trucks, each material truck is divided into 12-14 layers, and the layer spacing is about 8-12cm. The material truck must use 304 stainless steel screen to avoid production pollution to the material.

Third, the parameters of rose understanding

The wet and dry ratio of roses is about 4:1, and try not to exceed the recommended loading amount when installing flowers, so as not to affect the flower shape and dried flower appearance.

When drying, pay attention to the water tray in the drying room, if the water is full, it is necessary to replace the water tray in time, and the excluded water should be retained and collected, which is the raw material for extracting rose essential oil.

In fact, the drying process of roses is more complicated, and its temperature and humidity change greatly, so it is not easy to make high-quality roses. When the roses are initially dried, the temperature should not be too high at the beginning, and 60-70℃ can be used in the later period. During the drying of roses, the change of color and moisture should be observed at any time through the observation hole, so that the moisture is discharged well and the color is bright; The lowest layer of roses dried out of the box, the appropriate moisture content can be released after drying. Because the surface temperature of the rose is not too high, the chlorophyll change is less, the color is green and resistant to storage, the aroma loss is less, and the drying is uniform; At the same time, due to the fast evaporation rate of water, it is easy to form porosity, and the rehydration of the product is good, and the contents are easy to dissolve when making tea.
